How to restore Masala theme original look

I have the Masala theme for a new blog and tried a different background color just to see how it would look. I prefer the Masala original patterned background but could not figure out how to restore it. Can I get it back to the original background without having to delete my blog and start over? How would I go about doing this? (Note: I tried downloading the image files and moving them but they are all in random pieces, and it did not work for me). Thank you for your help!
